As new test cases are generated over time due to softwaremodifications, test suite may grow significantly. Because of time andresource constraints for testing, test suite minimizationtechniques are needed to remove redundant test cases. To achieve the goal, an improved artificial fish swarm algorithm (IAFSA) is proposed for the first time in this paper. The IAFSA constructs the initial population by greedy algorithm to reduce its scale, adjusts vision and step length dynamically and improves the basic preying behavior. The improvements restrain premature convergence and raise the convergence speed of the new algorithm. In other words, we can increase the probability to obtain the global optimum. The comparison of experiment results between greedy algorithm, AFSA and IAFSA demonstrates that the IAFSA has a better global stability to solve the test suite minimization problem effectively and obtain the minimization set of test suite significantly.
